Dec 04, 2020When it comes to ores with more than 20 grams of gold in every ton of ore, vat leaching is performed to ensure the cyanidation process. On the other hand, heap leaching is done to extract gold from ores of lower gold content. Since these ores contain gold of extremely low density, vat leaching calls for high amounts of solids and solutions.
